Dual Voltage Feedback Amplifier Is Low On Distortion

The LT1819 dual, unity-gain stable voltage feedback op amp has a total harmonic distortion of -85dB at 5 MHz at a voltage output of 2 Vp-p. Current consumption is just 9 mA with a 500_ load. The device offers a gain bandwidth product of 400 MHz and a slew rate of 2.5 kV/µs. Other features include a noise figure of 6 nV/_Hz at 10 kHz, 1.5 mV maximum input offset voltage, and a guaranteed minimum output current of 50 mA. Suitable applications include high-speed filters, a/d converter drivers, d/a converter buffers, and high-end video and wireless base station amplifiers. With operating temperature ranges of either 0_C to 70_C or -40_C to 85_C, the LT1819 is available in an industry-standard, eight-lead SOIC package. Price is $2.80 each/1,000.
